Introduction: The material for catalytic
converter substrate honeycomb ceramic is cordierite. The natural cordierite
exists very rare in nature, so most of cordierites are man-made substances. The
major features for such cordierite are low thermal expansion coefficient, good
thermal shock resistance, high anti-acid, anti-alkali and antii-erosion function
and good mechanical strength. The usual CPSI for catalytic converter substrate
is 400. The shape of honeycomb ceramic is round, racetrack, ellipse and other
special shape according to the customer's requirement in order to meet the
different cars models requirements.
